Despite the growing number of testosterone booster prescriptions, testosterone replacement therapies lack necessary research to prove efficacy, according to some doctors. In addition, Doctor Robert Schwartz of the University of Colorado Medical Center noted that clinical studies have not focused enough on potential testosterone booster side effects such as prostate cancer, blood clots and heart attacks.
In 2010, the National Institutes of Health conducted research which found a potential link between low testosterone drugs and heart attacks. Another study in 2014 found a similar link to severe side effects from Low T drugs. The health institute is currently conducting a trial to better determine testosterone booster risks and if the drugs possess the benefits some companies claim.
Despite medical concerns and insufficient research, testosterone booster prescriptions have more than tripled, becoming a multi-billion dollar industry. The increase may be partially attributed to several “Low T clinics” that prescribe testosterone boosters to patients, sometimes without conducting necessary testing to determine a patient’s testosterone levels.
